8 Claims. (Cl. 197-128) This'invention relates to adjustable, retractable paper stop means for businessmachines, said stop means being adapted to arrest each of a series of papers inserted in the machine in proper position for the printing of data in the desired position on said paper, to thereafter permit said paper to pass out of the machine, and to then arrest the next of said inserted papers in the proper position.

An object of the invention is to provide a retractable paper stop means which is quickly and easily adjustable to position the inserted papers to receive printing impressions at different deand reliable in performance of its intended functions.

One embodiment of. the invention isillustrated by way of example in the accompanying drawings, in which:

Figure 1 is a right-side elevation of a calculatins and accounting machine to which the invention has been applied, with the casing removed but omitting all but those of the-principal elements of the machine which will facilitate an understanding of the invention;

Fig. 4 is a perspective view illustrating the construction and arrangement of the adjustable, retractable paper stop means; and

Fig. 5 is an enlarged detail of Fig. 4. The invention is shown by way of example as applied to a well-known Burroughs high'keytrated by way of example is driven by an electric motor 20 through a single-revolution clutch 2| which, together with the electric current supply circuit of the motor, is controlled by the usual control link 22 from a main motor bar M and usually also from one or more additional motor bars and/or function control keys, not illustrated herein. On each elevation of the control link 22, the motor 20, through the clutch 2|, drives the shaft 23 and crank 24 through a single revolution to impart to the machine a cycle of operation comprising so-called forward and return strokes. The crank 24, through a link 25, oscillates an arm 26 about the shaft 21 on which it is journaled, clockwise as viewed in Fig. 1 in th forward stroke and counterclockwise in the return stroke of the cycle of operation. In the forward stroke of the cycle, the arm 26 rocks clockwise an arm 'wise. During the return stroke of the cycle,

springs 33, connected between the arm 29 and a fixed member of the machine frame, restore the arm 29, shaft 21 and shaft 32 to normal position, the return stroke being regulated by the usual dash pot, not shown.

Amounts and otherdata may be entered in the machine by depression of the proper keys in a pmrality of banks of keys on the keyboard of the machine prior to 'a machine cycle. During the amountor data-entering machine cycle, the .usual actuator racks 4| for banks of keys -40 in which keys have been depressed perform excur- 4| being determined by that one of the usual stop wires 42 which has been moved to limiting posiboard machine, but it will be apparent to those Gamer. Consrnucrron or MACHINE tion by depression of the respective one of the keys 40 in the corresponding bank of keys. The actuators II are carried by the forward arms of levers, the rearward arms of which each carry a series of type which are selectively positioned at the printing line in accordance with the positions at which the actuators 4| are arrested in the forward stroke of the machine-cycle, after which, and near. the end of the forward stroke, the type at the printing line are driven rearwardly by the usual printing hammers 45 to effect printing imin the machine may be also entered in one or more The Burroughs High Keyboard machine mustotalizers or registers such as the add and suband the rearward ends of members 89 which are tract crossfooter 46 or one of a line of adding totalizers or registers 41.

In total-taking and subtotal-taking machine cycles, the actuators 4| are adapted to be controlled in the usual and well-known manner by th pinions of the crossfooter 46 or by the pinions of a selected one of the adding registers 41, whereby said pinions also control the selective positioning of the printing type at the printing line so that the results of calculations performed on the machine are printed.

Front-feed paper equipment the main paper carriage frame 64. These papers B may include a sheet such as a journal sheet J passing around the platen and being permitted to remain in the machine throughout predetermined periods to receive thereon records of'all work performed on the machine during such periods, and papers such as bill forms or otherwork sheets W adaptedto be inserted in and also rockably supported on the shaft 88 and carry at their forward ends springs 90 which extend rearwardly over the shaft 88 and under the rod 86 to urge the rolls 85 to press the journal sheet J against the platen B0. Rotation of the shaft 63 by means of a finger lever to turn the flattened portions of the shaft from a substantially horizontal position to a substantially vertical position will retract the rolls from the platen to permit easy removal of the old and insertion of a new journal sheet about the platen when desired.

When the platen is in its normal rearward or front-feed position, papers W, such as bill forms or the like, may be front fed over a front paper chute 9!, which is supported on brackets 92 on the table 95 supported between the ends plates of the main carriage frame 64. When, during a machine cycle, the platen is rocked forwardly to printing position, it presses the front-fed sheet W and journal sheet against the pressure rolls 9! to removed from the machine in succession for the returned to printing position by rocking the platen frame 62 about the shaft i3. As shown in Figs. 2 and 3, a plate 65 secured to the lefthand end plate of the platenframe is connected to a spring 65 which urges the platen frame in a direction to carry the platen 60 rearwardly away from the printing type 44. The plate 65 also carries a stud 81 engaging the edge of a cam member 68 secured on a shaft "journaled in the main carriage frame 88. The shaft 10 has fixed thereon a bail II, the cross rod of which engages in an open slot in a rearwardly turned projection 12 of a slide 13 which is mounted for up-and-down sliding movements on the rear plate 14 of the machine frame. To the lower end of the slide 13 is secured a plate 15 carrying a stud ll engaging in a notch in the rear end of a r lever 11 pivoted intermediate its ends on the shaft 18 and carrying at its forward end (Fig. l) a stud l8 engaging in a cam slotin a plate 80 secured on the shaft 21.

The slide 13 is normally in its uppermost position, shown in dot-and-dash lines'in Figs. 2 and 3, whereby the cam member 88 is positioned to permit the platen 80 to occupy its rearward or front-feed position. The arrangement is such that, during the forward stroke of a machine cycle, the cam plate BI rocks the lever 11 clock- ,wise (Fig. l) to lower the slide 13, thereby rockingthe cam member 6! clockwise (Fig. 3) whereby the latter, acting on the stud 81, rocks the platen frame '2 to carry the platen 80 forwardly to printing position relative to the printing type.

The journal sheet J is normally continually pressed against the platen roller in feeding relation therewith by rear pressure rolls 85 (Fig. 3) rotatably mounted on a rod 86 supported at a plurality of points by the upper arms of bell cranks 81 which are adapted to be rocked about a shaft 88 supported in the end plates of the platen frame 62. The shaft 83 has flattened portions between the rearward arms of the bell cranks 81 grip the papers and support them in printing position prior to the operation of the printing hammers 45. As the platen roller '0 moves forwardly to printing position, the upper portion of the front-fed sheet W is wrapped partially about the platen by the lower edge of the front-feed paper chute 9| thereby facilitating clear, clean printing impressions on the inserted work sheet W., The usual ink ribbon (not shown) is provided for inking the type impressions on the work sheet. The record on the journal sheet is produced by means of a sheet of carbon paper C.

During the return stroke of the machine cycle, counterclockwise rocking of the shaft 21 and cam plate 80 by springs 33 causes the lever 'II to be rocked counterclockwise, thus returning the slide 13 to its upper position and permitting the platen frame 62 to be rocked about the shaft 83 by the spring 68 to return the platen ill to its rearward, front-feed or open-throat position to permit the front-fed work sheet W upon which entries have been printed to be replaced by the next work sheet on which it is desired to print entries.

The journal sheet J is line-spaced by rotation of the platen 60 by a line-spacing means comprising an arm lllll pivoted on the platen shaft BI and having pivoted on it a pawl ilil which is urged by a spring I02 into engagement with the teeth of a ratchet wheel I03 fixed on the platen shaft 6|. A link IN is pivotally connected at one end to the arm I00 and at its other end to one of a pair of brackets I05 on the carriage frame 64 so that each time the platen frame is rocked rearwardly to open-throat or front-feed position, the arm Hill is swung about the platen shaft II and the pawl l0! rotates the platen 60 to advance the journal sheet.

The brackets 92 on the carriage frame N may also su'bport a paper-holding means (Fig. 1) adapted to hold a supply of work sheets, such as bill forms or the like, in position to facilitate the insertion of successive sheets in the front-feed paper throat by the operator.

The paper carriage of the machine. illustrated in the accompanying drawings 'by way of exthe several column stops I II have been adjust-- ably secured on the stop shaft H2. The operator may manipulate the manual tabulating lever H4 (Fig. l) to rock the stop shaft H2 clockwise in Fig. l to lift the forward ends of the column stops III above the tabulating abutment H3 and then manually move the carriage to the desired columnar position where, upon release of the tabulating lever H4 by the operator, the usual spring H5 returns the parts, including the tabulating stop shaft H2, into position to cause the caniag'e to be held in the desired columnar position. It should be noted, however, that the adjustable paper stop means of the present invention may be employed also in machines having carriage tabulating mechanisms which operate automatically during successive machine cycles to move the carriage from column tocolumn and also with machines in which the paper carriage frame is fixed on the main machine frame and not movable laterally thereon.

While the platen-rocking or paper throat opening means illustrated in the accompanying drawings is arranged to cause the platen to be rocked out of printing position and the paper throat to be opened after operation of the printing mechanism in every cycle of operation of the machine, it is to be noted also that the ad justable paper stop means of the present invention described hereinafter are equally well adapted to be-used in machines in which the platenon each of the plates I23R and I23L being identical excepting that the stop means on one plate is the laterally reversed or mirror image of that on the other of said plates, a detailed description of the stop means carried by the plate I20L of Fig. 3 will sumce.

A vertical guide member I30 for the lateral edge of the front-fed sheet W is secured to a bracket member I3I having a pair of laterally turned lugs through each of, which passes a screw I 32 (only one of which is shown in Fig. 4), each of said screws also passing through an aperture in a. plate I33 and being threaded into 9. respective end'portion of a block I34 which is disposed in alongitudinal slot I35 in the plate I20L and also has lateral flanges underlying the plate I2IlL along the opposite lateral edges of the slot I35, whereby the plate I33, together with the paper guide member I30. may be adjusted longitudinally of the late I231- to the extent permitted by the length of the slot I35.

The plate I33'is releasably securable in adjusted position longitudinally of the plate I20L low, cylindrical boss 131 on the slide plate I33 I and has, within .the enlarged cylindrical bore in said boss, an annular enlargement I38 between which and the upper end wall of said boss I31 a compression spring 633 is confined, whereby the spring I39 urgesthe pin I38 downwardly through the lower open end of the boss I31". The plate I33 is formed with a plurality of apertures I43 along a line parallel to the edge of the slot I35 and adapted to receive the reduced lower end of the pin I33, whereby the slide plate I33 may be releasably secured in any position of adjustment longitudinally on the plate I20L. A

knurled cap nut I or the like threaded on an rocking and throat-opening means are arranged so and controlled so as to rock the platen out of printing position and open the paper throat after operation of the printing mechanism only in selected machine cycles, such as machine cycles Adjustable retractable paper stop means". I The paper stop means (Figs. 4 and 5) to'arrest upper, reduced end of the pin I33 may be grasped between the fingers of the operator and drawn upwardly against the tensionof the spring I33 to retract the lower end of the pin I33 from that aperture I43 in the plate I33 in which it is currently engaged, after which the plate I33 may he slid -to any desired position longitudinally of the plate I201, also by manipulation of the the front-fed sheets in proper positions to .re-

ceive the printed entries at the desired. vertical positions on said sheets are supported on apair of downwardly and rearwardly inclined plates I 23R and IZdL. each having a pair of downwardiy turnedlateral lugs IZI (Figs. 2 and 4) with forward projections which engage under the rearward edge of a crossbar 822 of angular section supported in the end plates of the carends in the brackets I33. Collars I33 secured to the lugs I33 have set screws threaded therein to secure the plates "BR and IQQL in the desired positions to which they may be adjusted laterally'of the carriage.

The adjustable, retractable; paper stop means knurled nut I, after which the nut I is released fr'om the fingersv of the operator-and the lower end of the in I33 is projected into another the upper arm of which is pivoted a paper stop 7 I43 which extends laterally inwardly through 'the space between the vertical paper guides I33 and I43 into the path of the front-fed papers, said stop member I43 having an extension I43 fonlneoi with a slot by which it is guided on a stud I47 securw in an upwardly oifset portion of the slide plate I33. The bell crank I44 Is-urged.

counterclockwise in Fig. 4 by a spring I43 secured to the lateral arm of the bell crank and to a stud in the slide plate- I33.

Between the knurled nut- III and a shoulder at the lower end of the upperreduced threaded portion of the pin I34 is secured an arm I3II- slotted arcuately about the center of the'stud' I43 to form a pair of I" (Fig. 5) en tion by means of a spring I51 connected between a stud on the slide plate I55 and a stud on the plate I33. It should be noted that, by reason of the construction just described, the lifting of the knurled nut MI by the operator to disengage the pin I35 from an aperture I40 in the plate IZOL also, through the arm I50, lifts the pin I52 to disengage it from the currently engaged notch I54 in the edge of the plate I55, so that the operator by grasping a single piece, the knurled nut I, may disconnect both of the pins I36 and I52 from both of the plates IZOL and I55 and move the plate I33 and stop I45 to any desired'position of adjustment where both of the pins I33 and I52 will be re-engaged with the respective plates IZOL and I55 upon release of said single piece I4 I.

It will be apparent also that, by reason of the construction above described, downward and rearward movement of the slide plate I55 will cause the bell crank I44 to be rocked clockwise in Fig. 4 to retract the paper stop I45 from the path 7 of the front-fed sheets. On the slide plate I55 is secured an angular bracket I59, on the upper forward portion of which is pivoted a bell crank I51, the lower arm of which is connected to one end of the spring I58 which is connected at its other end to 9. lug turned down from one edge of the slide plate I55, whereby the spring I53 normally yieldingly holds the lower arm of the bell crank I51 against an edge of the bracket I56. The forwardly extending arm of the bell crank carries a squared stud I59 adapted to be acted upon by the end of a cam arm I60 secured on a collar ISI, in which is threaded a set screw by which the collar I6I and arm I63 may be secured in any desired position on the shaft 10 which, as already described, is rocked-clockwise in Figs. 3 and 4 and counterclockwise in Fig. 2 during the forward stroke, and then returned counterclockwise in Figs. 3 and 4 and clockwise in Fig. 2 during the return stroke of each machine cycle.

With the parts in their normal position while the machine is at rest, that is, with the slide 13in its normal upper position and the platen 50 in its open-throat or front-feed, piston. the arms I50, of which there is one for each of the two retractable paper stops I45, are normally positioned as shown in Fig. 3, that is, with their rearward ends below the studs I59, and the two paper stops I45 are positioned as in Fig. 3 in the path of the front-fed paper. At this time the operator may take up a work sheet, such as a billform or the like, from the receptable 99 and drop it into the front-feed chute 9|, whereupon it will be guided into the open throat between the platen l0 and forward pressure rolls 93 and over the upper ends of the plates I20R and IZOL. As the frontfed sheet passes through the paper throat, its lower corners will fall against two paper stops I45 which, by reason of the adjusted positions of the slide plates I33, will arrest the front-fed sheet, as shown by the paper W in Fig. 4, in the correct position to receive a printed entry at a desired vertical position thereon.

After entering the appropriate data on the keyboard of the machine. the operator may give the 75 'machine a cycle of operation by depression of the motor bar M whereupon, through the means previously described, the shaft 15 will be rocked clockwise in Figs. 3 and 4 (counterclockwise in Fig. 2) to rock the platen frame 62 and platen 60 to the closed-throat or printing position whereby the front-fed sheet W will be gripped between the platen and the front pressure rolls 93 and held in' printing position, with the aid also of the lower edge of the front-feed paper chute. During this movement of the shaft 10 the arms I50 engage the studs I59 and cam the bell cranks I51 counterclockwise in Fig. 4 until the ends of said arms I60 pass the studs I59, whereupon the springs I58 return the bell cranks I51 and studs I59 to their normal positions. Then, near the end of the forward stroke of the cycle the printing mechanism operates to print the appropriate data along the proper line on the front-fed work sheet W.

At the beginning of the return stroke, through the means already described, the shaft 10 is rocked counterclockwise in Figs. 3 and 4 (clockwise in Fig. 2) to permit the platen 60 to rock rearwardly out of printing position to its openthroat or front-feed position. Simultaneously, the ends of the arms I60 act on the studs I59 and, as the bell cranks I51 are prevented from rotating clockwise by reason of the engagement of their lower arms against the edges of the brackets I 55, the slides I are cammed down wardly and rearwardly and, because of the engagement of the pins I52 in notches in the edges of the slides I55, the bell cranks I44 are rocked to move the paper stops I45 laterally outwardly from beneath the lower corners of the work sheet W as the paper throat opens. The paper on which the printed entry has just been made is thereby permitted to slide downwardly and rearwardly on the plates IZOR and IZDL between the guides I30 and into a receptacle I65 supported between the brackets I05. It will be noted that the papers enter the receptacle face down and are therefore stacked in the order in which they pass through the machine.

As the shaft 10 completes its movement at the end of the machine cycle the ends of the arms I pass the studs I59, thus permitting the slides I55 to be returned upwardly and forwardly to their normal positions by the springs I53 which, with the aid of the springs I48, will project the paper stops I45 again laterally inwardly into the path of the front-fed papers.

It will be noted that the stops I45 are retracted only very briefly and sufficiently to permit the sheet upon which an entry has just been printed to commence its movement downwardly and rearwardly out of the carriage. faces of the paper stops I45 are inclined outwardly and upwardly so that, when the stops are returned inwardly toward their normal positions, their leading lower edges will pass under the edges of the sheet passing out of the paper carriage and lift the lateral edges of the sheet above the stops, if the sheet has not already passed beyond the stops. The very brief retraction of .the stops and the immediate return thereof into effective position insures that the next work sheet to be dropped into the frontfeed throat by the operator will be stopped in the proper position by the stops, no matter how closely the newly inserted'paper may follow the paper which is dropping out of the carriage.

It will be apparent that the adjustable retractable stop means' as described above are'readlly- The facing inner and out oi' said path, and a singlemanipulative means to operate saidsecuring andconnecting.

adaptable for use with forms oi varying dimensions, and with forms upon which data are to be enerted in various vertical and lateral positions. -To adjust the mechanism for forms 01 varying widths and for various columnar rulings on the form, it is only necessary to loosen the set screws in the collars I and ISI and to shift the plates IZIIR and IZIIL and arms I84 laterally to the appropriate positions on theshafts I24 and 10, where they may be secured by retightening the set screws. To adjust the mechanism for various horizontal rulings on the forms, 1. e., to position the forms to receive printed entries in desired vertical positions or lines, it is only necessary for the operator to lift the knurled nuts It and, through these same members, shift the slide plates I33 longitudinally of the plates I2IlR. and I 20L to place the stops I45 at the desired new vertical positions where the operator may release the knurled nuts I to permit the pins I and I52 to be re-engaged in the appropriate apertures I and notches I 54 by the springs I39.

While the form of construction above de- .scribed is admirably suited for the purposes and functions mentioned. it will be readily apparent to those skilled in the art'that the invention may I be embodied in various other constructional forms within the scope of the appended claims.
